Tradition and Future
Groz-Beckert
Textiles are everywhere and are found in a wide variety of shapes and functions in all areas of life: Fashion, sports and leisure, home textiles, flooring or in architecture. And textiles are also indispensable for mobility – from cars to space travel – and for health.
Groz-Beckert manufactures machine needles, precision parts and precision tools and offers supporting services for all aspects of the textile industry, from fashion, home and domestic textiles to technical textiles.
Technology and Development Center
Groz-Beckert represents reliable product quality and customer service in the world of textiles. The Technology and Development Center (TEZ) was opened in 2010 in order to develop new development and application fields for textiles in cooperation with customers and partners. Not only is the TEZ furnished with state-of-the-art equipment, it also provides the perfect environment for bundling the competencies and knowledge of Groz-Beckert. As a future-oriented company, Groz-Beckert places great value on the research and continued development of new technologies and application fields in the textile industry.

The Felting product sector
Far more than just products
Groz-Beckert not only develops, produces and sells products for the nonwovens industry, it also provides a range of services for machine manufacturers and nonwoven fabric producers. The Technical Center Felt-ing at the Groz-Beckert Technology and Development Center (TEZ) is equipped with a state-of-the-art staple fiber needle punch line, as well as various testing de-
vices for textile-related physical property evaluations under ideal analysis and testing conditions. The staple fiber needle punch line also provides the requisites to simulate production processes and develop process knowledge, in order to provide answers to varied questions.The central goal of the product division is to achieve process optimization around the manufacture
of nonwovens and the consistent expansion of overall expertise in the field of nonwoven bonding.
In 1980, Groz-Beckert extended its portfolio to include products for the nonwovens industry. Over time, the portfolio has come to include felting and structuring needles, jet strips, high-quality tools and accessories to create surfaces, as well as comprehensive services for felting products. Groz-Beckert provides to the nonwoven industry production solutions with any type of fiber material, be they wood chip fibers, animal fibers, natural fibers, mineral fibers, or synthetic fibers.

The right tool for any application
With the mechanical nonwoven binding process, fibers are transported by felting needles or hydroentanglement, and incorporated into the nonwoven web. The nonwoven fabrics produced in this way, are used in a wide variety of fields including medicine, cars and aircraft, geotextiles, filtration, home furnishings, and felts for paper production machinery. Wide-ranging fields of application call for suitably specialized tools. This is why the Groz-Beckert portfolio of felting and structuring needles encompasses around 2,000 different needle types. Depending on the materials used, the requirements of the production processes and the end products, the most suitable needles need to have certain characteristics and ”talents“. For jet strips, production is subject to customer request. The individual configuration and depth of variation provide a number of different options.
10
The portfolio encompasses:• 2,000 needle types for all applications• World market's most extensive production range• Special needle geometries coordinated to
wide-ranging product segments• Needle designs to address the most stringent
demands
Depending on the fiber materials and required properties of the end product, different needle types are appropriate which differ in terms of their length, the shape of the working part and the distribution or properties of the barbs. Groz-Beckert offers many different high-performance felting and structuring needles.

In order to allow the stringent demands imposed a wide range of applications, in terms of surface properties, tear resist-ance, uniformity, minimal damage to the fiber and substrate material as well as service life, felting needles with a variety of working part shapes are used.

Groz-Beckert offers four different barb styles.
In felting needles, the barbs are responsible for fiber transport. The dimension and shape of the barbs are highly significant in determining the efficiency of the needling process, as these are used to transport and entangle the nonwoven web. The size of the barbs is defined by the barb depth and kick-up, and significantly affects the fiber pickup. The undercut angle defines how well the fiber is retained by the barb. The formation of fiber loops brings about an increased degree of bonding in the fabric. As a result, higher fiber-to-fiber friction forces are created, which determine the final strength and volume as well as all other mechanical properties of the nonwoven fabric.

Structuring needles
A distinction is drawn in structuring needles between fork and crown needles. The task of structuring needles is to structure already bonded nonwoven fabric in special machines. The surfaces are produced with a velvety or grainy character, or also feature geometric or linear patterns.
Fork needles have a shank with single or multiple reduction and cylindrical working part. The essential functional element is the fork opening on the working part.
Crown needles are structured in the same way as felting needles, with the only difference being the barb arrangement. There is precisely one barb located on each edge of the working part. The short distance from the tip to the barb is the same for all three barbs. This ensures an even loop formation.

Jet strips
Jet strips are used for hydroentanglement, the so-called spunlace technique. As with felting and structuring needles, various jet strips are needed depending on the desired properties of the end product. Groz-Beckert offers jet strips in various dimensions and materials.
The portfolio includes jet strips with the following specifications:• Overall length: 80 mm to 6,200 mm• Number of nozzles: 40 to 20,000 nozzles• Number of rows: 1 to 5 rows• Nozzle diameter: 0.08 mm to 0.22 mm

Fields of application for felting and structuring needles as well as jet stripsThe areas in which felting and structuring needles, as well as jet strips are used, are almost limitless. Bonded nonwovens are also used in many technical areas due to their durability, appearance, functionality, low weight, and inexpensive production.

App myGrozBeckert
Your personal work tool
As it is one of the most essential prerequisites of working effectively, Groz-Beckert traditionally places great importance on sharing knowledge and experience. In order to provide mobile access to this know-how and make it available offline, Groz-Beckert developed an app in 2011 that contains well-founded knowledge along the textile value chain and about the company.
Since then, myGrozBeckert has continuously been developed further, and as part of the 2017 relaunch a completly customizable navigation was implemented.
This allows users to save favorites and preferred top-ics themselves, and change them any time as needed. This is how myGrozBeckert becomes a personal and individually configured work tool.
myGrozBeckert works with all iOS and Android smart-phones and tablets, and is available in German, Eng-lish, and Chinese. The free app can be downloaded through the Google Play Store, the Apple App Store or through various Chinese app stores.
